Less than a decade ago, McLaren Automotive as a carmaker didn't exist. The company most famously associated with Formula 1 and the McLaren F1 hypercar only collaborated with other carmakers on special projects. In only a few years, the company has produced 22 unique models in the process of setting a new sales record for 2018 of 4,863 cars, McLaren as a supercar company is here to stay.

Each McLaren road car is a work of art, packed with powerful engines, and yet, the aftermarket tuners cannot resist "improving" the breed, producing some of the sickest McLaren's we've ever seen.

McLaren's GT is a more practical and luxurious sports car with a little less performance.

Vivid Racing

Amusingly McLaren designed the 570S as a more practical supercar that owners could use daily, softening the ride while adding more luxurious cabin trim levels. The reality is the 570S makes do with just 562hp from its twin-turbocharged V8 as a result owners will only see a maximum top speed. If McLaren was serious about 570S being a softer sports car then why build the track-focused GT4 version?
